COFFEE-POT.v

SPECIFICATION forming part of Letters Patent No. 299,706, dated June 3,1884.

Application filed September 28, 1883.

v To all whom, it may concern.

Be it known that I, HUMPHREY P. WEB- STER, of Boston, in the county ofSuffolk, State of Massachusetts, have invented a certain new Likeletters and figures of reference indicate" corresponding parts in thedifferent figures of the drawings.

My invention relates to that class of coffeepots which are provided withfilters; and it consists in a novel construction. and arrangement of theparts, as hereinafter more fully set forth and claimed, by which a moreeffective article of this character is produced than is now in ordinaryuse.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following err-- planation,,its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the body of the pot, B the handle, 0 thecover, and D the spout or nose. The body is preferably composed ofporcelain, china, or some vitreous or earthen substance to preventinjuring the coffee, but maybe constructed of tin, britannia, or anyother suitable materials, if preferred. The upper portion of the bodyfrom the line 00 x is slightly flaring, the object being to prevent thefilter from falling too low in the body and to enable it to be adjustedat any desired point therein.

The filter consists of the sack D, hoop E, handle F, and springsG, thesack being composed of flannel or any suitable material for the purpose.The hoop is formed of a thin narrow strip of metal, preferably tin, andis vertically or transversely corrugated,its ends, which overlap and areconnectedby the twines or threads m,'being provided with a series of (N0model.)

holes, 11. The springs G, which are preferably composed of thin'fiatstrips of tin, and have their upper ends riveted or soldered-to thehoop, project downwardly and are curved out wardly, as shown in Fig. 1,the sack being attached to the hoop by sewing or in any other suitablemanner, so as to cover the upper ends of the springs.

In coffee-pots of this character where the hoop of the sack fits closelyin the body of the pot, difficulty is sometimes experienced in pouringout the liquid where the meshes of the sack have become filled with fineparticles of coffee, the tendency being to form a vacuum below thefilter. This objection I overcome by corrugating the hoop E, thecorrugations permitting the air to pass down freely on all sides of thefilter, and thereby enabling the liquid to be poured from the potwithout difficulty. The corrugations also perform another importantfunction, as they enable a much stronger joint to be made at theoverlapping ends of .the hoop than is possible where a plain hoop isused, the corrugations of the overlapping parts intermeshing with eachother in such a manner that when the ends are bound together by thetwine or threads on, or in any other convenient way, they cannot betwisted out of place, but maintain a proper position with respect to thebody of the hoop.

The springs G are designed for steadying the filter in the body of thepot, and the handle F for inserting and removing it; but both the handleand springs may be omitted, if desired. In coffee-pots provided with afilter of this character and having a straight body it is very difficultto adjust the filter so that it will remain permanently suspended at anydesired point, being liable to drop down into the bottom of the vessel,especially when carelessly used. To overcome this objection I constructthe upper portion of the body ofthe pot slightly flaring, whereby theadjustment of the filter in any required position is renderedcomparatively easy, the hoop E being readily enlarged or contracted inaccordance with the height it is desired to have it stand above thebottom of the pot, and the fiaringsides preventing it from falling belowthe position it is designed to occupy. The flare of the pot may commeneeat the bottom and extend to the top, if desired,al though I deem itunnecessary to have the flaring portion extend below the inlet to thespout or nose B.

I do not confine myself to providing a coffee-pot constructed,asshown,with a filter having a corrugated hoop, as a plain hoop may beused with a flaring pot, if desired,although I deem a corrugated one farpreferable; neither do I confine myself to using a filter having thecorrugated hoop with a flaring pot only, as it is well adapted forstraightpots, the corrugations forming a series of curved springs whichyield to permit the insertion of the filter in the body of the pot andexpand to hold it any desired position, which a plain hoop will not do;nor do I confine myself to so constructing the hoop that its ends may beoverlapped, as it maybe made continuous, if desired.

I am aware that a plain cylindrical coffeepot filter has been made, themeeting-edges of which are adapted to overlap.

I am aware that a coffee-pot filter has heretofore been provided with unvardly-inclined diverging springs attached to the top cover of thestrainer but in that construction the strainer is projected too far intothe coffee-pot and the coffee is submerged in and acted upon directly bythe water contained in the pot,instead of being acted upon by the steamto form what is known as drip-coffee, which latter is the preferableinfusion.

Having thus explained my invention, what I claim is- 1. A filter foreofleepots, consisting of an adj ust-able hoop, a filtering-sacksuspended therefrom, and springs attached at their upper ends to saidhoop and extending outwardly and downwardly therefrom outside of thesack, substantially as described.

2. The combination, with a filtering-sack for coffee-pots, of acorrugated adjustable hoop for supporting said sack, the ends of saidhoop being overlapped, intermeshed, and attached together, substantiallyas described.

3. The combination, with a coi'feepot, of a filter consisting of anadjustable hoop, a filtering-sack suspended therefrom, and springsattached at their upper ends to said hoop and extending outwardly anddownwardly therc from outside of the sack, substantially as de scribed.
